The adoption of improved cook stoves is critical performance parameters of the cooking system that must be monitored. No stove program can achieve its goals unless people initially accept the stoves. In Ethiopia agricultural expansion, overgrazing and fuel-wood collection are the causes of deforestation and forest degradation which contribute to carbon emission. To mitigate this, promoting improved cook stove (ICS) is an intermediate solution. Thus, the overall goal of this study was to determine household adoption of improved cook stoves and their role in climate change mitigation. A survey was conducted with a structured questionnaire for 334 households that were systematically selected from three kebeles. Household survey has been supplemented with key informant interview (KII) and focus group discussion (FGD). Data were analyzed by using descriptive statistics, chi-square, Independent T-test, and binary logistic regression. About 75.7% of respondents in the study area have adopted ICS. About 0.201±x tons fuel wood was consumed per year in the traditional three-stone cook stove was significantly lower than 0.143±x tons of fuel wood consumed per year if every household were using Mirt’ stove. Consequently, the GHG emission mitigation potential of Mirt was estimated to be 10.84t CO2eq. The binary logistic regression result indicated that agro ecology, marital status, income, member of social organization, social factors, price and type of fuel wood were factors that influence adoption of improved cook stoves at 1%, 5% and 10% level of significance. Based on the study result, improving the awareness of the community, and increasing the supply of ICS would have significant impact to enhance adoption of ICS and thereby enhance mitigate GHG emission.
